Professor Wiseman wants to makes something creative for the bake sale at Betsy's school. But she believes that the key to cooking is to experiment with different amounts of different ingredients and as a result her cakes come out floppy, gross, and VERY sticky. When Professor Wiseman and George visit Chef Pisghetti he says that cooking is not about testing and experimenting like science and you need to follow a recipe exactly for the food to come out right.
